In 1742, a highland Andean named Juan Santos led a group of mainly Asháninka and Yanesha warriors against a handful of isolated Franciscan missions in the central high jungle of Peru. Over the next ten years the rebellion smoldered, occasionally sparking to life, as Santos's forces pushed the missionaries based out of the College of Santa Rosa de Ocopa (near Jauja, Peru) back to the highlands. The uprising culminated in a brief foray into the highlands, but never effectively reached beyond the security of the densely vegetated high jungle, known locally as the central montaña region. Despite its modest accomplishments, the rebellion secured autonomy for the combatant nations during the rest of the colonial period.
